1) Gardener A can mow an entire lawn in 3 hours. Gardener B can mow the same lawn in 5 hours. How long will it take them to mow the lawn if they work together?
\n" ); document.write( "Let x = time (hours) it takes working together
\n" ); document.write( "then
\n" ); document.write( "x(1/3 + 1/5) = 1
\n" ); document.write( "multiplying both sides by 15:
\n" ); document.write( "x(5 + 3) = 15
\n" ); document.write( "x(8) = 15
\n" ); document.write( "x = 15/8 hours
\n" ); document.write( "or
\n" ); document.write( "x = 1.875 hours
\n" ); document.write( "or
\n" ); document.write( "x = 1 hour and 52.5 minutes
\n" ); document.write( ".
\n" ); document.write( "2)To paint a house alone it would take Mario 3 days, Danny 4 days and Lito 6 days. How many days should it take them to paint 3 houses if they all work together?
\n" ); document.write( "Let x = time (days) it takes working together
\n" ); document.write( "then
\n" ); document.write( "x(1/3 + 1/4 + 1/6) = 3
\n" ); document.write( "multiplying both sides by 12:
\n" ); document.write( "x(4 + 3 + 2) = 36
\n" ); document.write( "x(9) = 36
\n" ); document.write( "x = 4 days
\n" ); document.write( " \n" ); document.write( "
\n" );
